Set. x341 BY.4/G.14.10.36. 362 PHANTOM 111 - BROKEN SERVO LEVER. Sg.{Arthur F. Sidgreaves - MD}3/E.13.10.36. The design which Phan.111 follows is the 25/30 and the Bentley. In the case of the Phan.11. the lever was blanked out from a sheet steel instead of being forged, but the 25/30 have precisely the same features in every respect. In the case of the Phan. 111, however, the depth of the lever is considerably increased, the Phan.111 being 80% stronger, the material being the same. The lever for the 25/30 and the Bentley was forged out at Hughes Johnson, and the Lever for the Phantom 111 was forged by the Midland Stampings Co. In regard to the matter of the responsibility of the inspection, Wor.{Arthur Wormald - General Works Manager} is dealing with this side of the matter. BY.{R.W. Bailey - Chief Engineer} | ||
